Propulsion Sub Systems

Propulsion Sub Systems is a good Mechanical Engineering project for final year and third year Seminar topic.Spacecraft are provided with sets of propulsive devices so they can maintain three-axis stability, control spin, execute maneuvers, and make minor adjustments in trajectory. You can also Subscribe to FINAL YEAR PROJECT'S by Email for more such Projects and Seminar.Other components of propulsion subsystems include propellant tanks, plumbing systems with electrically or pyrotechnically operated valves, and helium tanks to supply pressurization for the propellant. Some propulsion subsystems, such as Galileo's, use hypergolic propellants--two compounds stored separately which ignite spontaneously upon being mixed in the engines or thrusters.
